SINOPSIS

Detailed measurements in a horizontal channel flow laden with solid particles with different size and loading ratio were performed using phase-Doppler anemometry. The data were required for the validation of numerical calculations based on the Euler/Lagrange approach. In this approach the Reynolds-averaged continuity and Navier-Stokes equations in connection with a full Reynolds-stress model constitute the basis. The conservation equations of course include appropriate terms for two- way coupling. For modelling the particle phase in the Lagrangian frame all relevant effects are accounted for, such as, transverse lift forces, turbulent dispersion, wall collisions with roughness, and inter-particle collisions. Comparison of measurement and numerical calculation is presented for different particle diameters and mass loading. The agreement was found to be reasonable good for both mean and fluctuating velocities.
